[Nouveau] [PATCH mesa 0/5] nouveau: codegen: Make use of double immediates

[Hans de Goede]

Hi All,

This series implements using double immediates in the nouveau codegen code.

This turns the following (nvc0) code:
      1: mov u32 $r2 0x00000000 (8)
      2: mov u32 $r3 0x3fe00000 (8)
      3: add f64 $r0d $r0d $r2d (8)
    
Into:
      1: add f64 $r0d $r0d 0.500000 (8)

This has been tested with the 2 double shader tests which I just send to
the piglet list. On a gk208 (gk110 / SM35) card, and by checking the output
of nouveau_compiler with both nvdisasm and envydis on gf100 / gk104 / gm107.

Regards,

Hans
